Terrestrial hydrology is central to the Arctic system and its freshwater circulation. Water
transport and water constituents vary, however, across a very diverse geography. In this …

Atmospheric humidity, clouds, precipitation, and evapotranspiration are essential
components of the Arctic climate system. During recent decades, specific humidity and …

Arctic rivers drain~ 15% of the global land surface and significantly influence local
communities and economies, freshwater and marine ecosystems, and global climate …

Rivers integrate processes occurring throughout their watersheds and are therefore
sentinels of change across broad spatial scales. River chemistry also regulates ecosystem …

As the permafrost region warms, its large organic carbon pool will be increasingly
vulnerable to decomposition, combustion, and hydrologic export. Models predict that some …

In this paper, we develop and apply a framework for estimating the potential global-scale
impact of reservoir construction on riverine sediment transport to the ocean. Using this …

Synthesis of river-monitoring data reveals that the average annual discharge of fresh water
from the six largest Eurasian rivers to the Arctic Ocean increased by 7% from 1936 to 1999 …

A new dataset of historical monthly streamflow at the farthest downstream stations for the
world's 925 largest ocean-reaching rivers has been created for community use. Available …

The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and
human/cultural systems that may be irreversible on century time scales and have the …

Executive summary Physical and biological systems on all continents and in most oceans
are already being affected by recent climate changes, particularly regional temperature …
